Project description:Spermatogonia expressing the highest levels of ID4 (ID4-GFP Bright) represent a population highly enriched for spermatogonial stem cells (SSC) while those expressing lower levels (ID4-GFP Dim) are the putative immediate progenitors. Comparing the transcriptome of these populations can provide insight into the SSC to progenitor transition.
Project description:To evaluate the impacts of Dnmt3A mutation in the methylome of male germ cells, mutant and control whole genome bisulfite sequencing experiments were conducted starting from genomic DNA obtained from FACS-sorted germ cells.
Project description:To reveal distinct transcriptome changes among ID4-EGFP-bright adult mouse spermatogonia associated with mTORC1 activity, single-cell transcriptomes were generated from GFP-bright/CD9-bright spermatogonia from adult mice in three groups: control (untreated), 2 days of Rapamycin treatment (Rapamycin) and 2 days Rapamycin plus 1 day washout (Rapamycin_Release). Based on transplantation studies performed previously, ID4-EGFPbright cells are highly enriched for SSCs. We used the 10x Genomics Chromium to perform single-cell RNA-seq.
Project description:Mice that constitutively overexpress ID4 in germ cells have impaired spermatogenic lineage development. The transcriptome of ID4-GFP+ spermatogonia from testes of ID4 overexpression animals was compared to the ID4-GFP+ population from controls
Project description:To reveal distinct transcriptomes associated with spermatogonial stem cell renewal vs. initiation of differentiation, single-cell transcriptomes from P6 ID4-EGFP+ spermatogonia (sorted for brightest or dimmest) or unselected testis cells were used for Drop-Seq analysis. The GFP-bright and dim phenotypes exhibit distinct fates when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the 10x Genomics Chromium (a commercial Drop-Seq variant) to perform single-cell RNA-seq
Project description:To reveal distinct transcriptomes associated with various spermatogenic cells, including spermatogonial stem cells and all of their subsequent progeny, single-cell transcriptomes from Adult ID4-EGFP+ spermatogonia (sorted for brightest or dimmest), StaPut-enriched spermatocytes and spermatids, or unselected steady-state spermatogenic cells were used for 10x Genomics analysis. The GFP-bright and dim phenotypes exhibit distinct fates when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the 10x Genomics Chromium (Drop-Seq) to perform single-cell RNA-seq
Project description:The function of ID4 in CLL development was studied in vivo using TCL1 transgenic mouse model that develop leukemia similar to human CLL. TCL1 mice with ID4 single knockout gene have accelerated CLL progression. Results from the animal study suggest ID4 as a tumor suppressor gene that might regulate cell proliferation and apoptosis in B lymphocytes. Gene expression in CD19-positive splenic B cells collected from 1-month old ID4+/-TCL1-tg and ID4+/+TCL1-tg mice was compared by microarray, the goal is to find ID4-regulated genes involved in CLL development.
